BEIJING — Three Chinese citizens have been killed in an attack in an apartment building in the Afghan capital, Kabul, according to Chinese state media reports.

Two women and one man were killed in the building on Thursday and two other Chinese men were missing, the official Xinhua News Agency reported late Saturday. Citing the Chinese Embassy in Afghanistan, Xinhua said one of the missing men had been found alive and taken to a safe place.

State broadcaster China Central Television had reported Saturday that the body of the second man had been found, but on its main lunchtime broadcast Sunday said the second man was still missing.

CCTV said the deceased were engaged in privately run small-scale business in Afghanistan.

No statement was available on the embassy's website and no potential motive was mentioned.

Xinhua said it remained unclear whether the attack was purposefully targeting Chinese nationals.

Overseas attacks on Chinese citizens have risen in recent years as more Chinese travel for tourism and more work in other countries.
